If Et = 12 V and It = 3 A, Rt equals?

Explanation:
Ohm's law ties together voltage, current, and resistance: V = I × R, so R = V / I. With a voltage of 12 V and a current of 3 A, the resistance is 12 / 3 = 4 Ω. Keeping the voltage fixed and changing the current would change the resistance accordingly (e.g., 2 A would give 6 Ω, 4 A would give 3 Ω). So the resistance is 4 Ω.
